Given an isosceles triangle, find the measure of all of the side lengths

The video tutorial explains how to solve for X in an isosceles triangle problem. It begins by discussing the properties of isosceles triangles, specifically focusing on congruent sides. The instructor sets up an equation based on the given triangle sides and solves for X using inverse operations. Finally, the video demonstrates how to calculate the lengths of the triangle's sides using the solved value of X.

If X equals 2, how do you find the lengths of the sides RT, TS, and RS?

Explain why the lengths of TS and RS must be equal in an isosceles triangle.
